How many bacterial species are genetically accessible/transformable at this time - (Jul/14/2016 )

This is a somewhat simple question but the answer has eluded me. 

How many bacterial species have been successfully genetically manipulated or transformed with man made DNA? Irrespective of transformation method.

I presume this would be a very small number in the scale of cultivable bacterial species.

Thanks!

Actually this is quite a hard question to answer - many might have been done in the context of a lab and not published, you might be better off asking in terms of genera. Even so, the answer could only be found by trawling the scientific literature.

I think as a general answer you could look at the genera that are capable of transformation naturally and work from there.

That's a good suggestion, thank you.

I managed to find one recent publication suggesting approx 80 naturally competent species (http://www.nature.com/nrmicro/journal/v12/n3/full/nrmicro3199.html)

So a conservative estimate considering artificial transformation methods might put those successfully transformed species at <100??

As you mention it would take serious trawling of the literature to get a specific figure, I just do not want to include a "guesstimate" in a presentation if a better number is out there.
